Dewalt DWE402K Angle Grinder Review

Dewalt DWE402K Review

Quick Overview





  • High performance
  • Solid durability
  • Reassuring warranty


  • Only comes with one speed
  • Comes with a paddle switch instead of a slide one

The Dewalt DWE402K runs on a good 11 Amp motor, a 4.5-inch blade, and can reach speeds up to 11,000 revolutions per minute.This makes it great for light to medium intensity jobs.

The Dewalt DWE402K will serve you quite well if you’re looking for a good angle grinder to use for adding finishing touches or details to your weld or to work on low-profile metals such as copper.

The trademark dust ejection system was designed especially to keep all types of debris from the case of the gear. It also deflects debris away from the grinder’s motor. This extends your level of protection as well as the longevity of the angle grinder.


Dewalt DWE402K In-Depth Review

It works on both AC and DC to give you an extra degree of freedom.

The good thing about the gear case is that it’s quite low-profile which allows you to fit it into tighter spaces.

Its features make it suitable for both a beginner or a pro. However, the paddle switch wasn’t the most clever alternative to the slide switch.

But the safety lock-off that prevents any unintentional start-up is good enough to ensure your safety.

The lock-on option is also a nice addition that allows you to work for extended periods of time without having to keep your finger on the trigger.

Furthermore, the safety lock-off and lock-on switch prevent any unintentional start-up to ensure your safety.

It also comes with a guard that can be rotated from a one-touch system up to 360 degrees according to your own convenience.

A drawback to the Dewalt DWE402K is that it doesn’t give you the option to work with different speeds. This limits your work to some degree, as you can’t use it for a variety of functions like cutting and cleaning but only for carving some details here and there.

The Dewalt DWE402K is also provided with a premium-quality bevel gear system that works on channeling more of its power to the grinding blade instead of the motor.

Finally, the Dewalt DWE402K comes with a 3-year limited warranty, a year of free service, and 90-day money back guarantee. All of these reassurances speak volumes of its durability and reliability.
